Foreword
This standard is one national standard "slotted screw" product family standard. The series includes.
a) GB/T 65-2000 Slotted cheese head screws;
b) GB/T 67-2000 Slotted pan head screws;
c) GB/T 68-2000 Slotted countersunk head screws;
d) GB/T 69-2000 Slotted countersunk head screw;
e) GB/T 832-1988 slotted perforated spherical cylindrical head screws;
f) GB/T 878-2007 Slotted headless screws;
g) GB/T 883-1988 Slotted large raised cheese head screws;
h) GB/T 947-1988 Slotted large head screws.
This revised standard adopts ISO 2342.2003 "no headband slotted screw rod" (in English), the main changes are as follows.
--- Normative reference document, instead of using our standards corresponding to international standards;
--- ISO 2342 non-ferrous metal screws are not given a specific level of performance, this standard shall be specified (see Table 2);
--- ISO 2342 does not provide packaging technology requirements, the standard to be prescribed (see Table 2);
--- ISO 2342 surface treatment not specified, this standard shall be specified (see Table 2,5.2);
--- ISO 2342 does not provide for a simplified mark, the present standard of GB/T 1237 to simplify the principles given simplified markup example (see 5.2).
This standard replaces GB/T 878-1986 "threaded cylindrical pin."
This standard compared with GB/T 878-1986 main changes are as follows.
--- Products sold by the screws to the product and modify the standard name;
--- Press thread size adjusted series and nominal diameters range (see Table 1);
--- Press screw product specifications series and adjust the length of the range (see Table 1);
--- Press screw product provides the technical conditions (Table 2).
The standard proposed by China Machinery Industry Federation.
This standard by the National Standardization Technical Committee fasteners (SAC/TC85) centralized.
This standard was drafted. Productivity Promotion Center in the machine.
This standard replaces the standards previously issued as follows.
--- GB 878-76, GB/T 878-1986.
